To all whom it may concern Be it known that I, BENJAMIN B. AV RY,

' a citizen of the United-States, residing at New York city, in the county of New York' and State of New York, have invented certain new and useful Improvements in Drinking-Cups, of which the following is a specification.

' that it may be discarded after it is once used.

Iamaware that it is not new to provide a drinking cup from a folded blank having its longitudinal edges folded a plurality of times, so as to form a cup, which'form of cup. is shown inthe Powers Patent No. 1,107,347 owned by my. company, but the primary object of my invention, however is to improve that cup and so look the folded edges that they will not become separated in use, which is not provided against in the Powers cup, and this I accomplish in various ways hereinafter referred to.

In the drawings accompanying and forming part of this specification,

igures 1, 2, 3 -and 4 illustrate different forms of blanks from which the cup can be made; Fi s. 5, 6 and 7 illustrate perspective views of t e cup made from the blank shown 4 in Fig. 1; Figs. 8 and 9 illustrate cu smade from the blank shown in Fig. 2; igs. 10 and '11 illustrate cups which may also be made from a blank similar to that shown in Fig.-j 2. Figs. 12, 13 14 and 15 illustrate c lmdrical cups whic may be made from t e style of blank shown in Fig. 4.

Similar letters of reference indicate corresponding parts in the several figures of the drawings;

the separation thereo I v vented, which" as herembefore stated, is the In the various forms of'cups shown, how-. ever, the folded side ed es are so looked that is practically pre primary object of the 'present improvement.

. In the present improvementany 'desired number, of cu s may be. produced successivel'yfrom a ong web "of paper by -simplycutting therefrom rectangular blanks and foldin them in the manner about to be'describe Specification of Letters Patent. I

.In making thecups shown in Figs. 5, 6 and 7, each cup blank cut from a web of paper a 1s of suflicient length to form two PatentedJunse 1, 1920. v

sides 0 and d, and a flap-b. The sides are folded midway of their lengthas at which sides are then folded lengthwise f their length as at a to form a plurality of that the form of cup illustrated in Fig; 5 is much the preferable construction. When the. cup is folded as just described, the flap b is then folded down along the lineFf over one side of the cup as illustratedjin. igs. 5,

6 and 7, whereupon the side folds are locked practically against separation. This locking flap b not only forms a locking means for the side folds, but it also constitutes a reinforced edge for the cup as well as a thickened edge for the lipsof the user. In 2 other words, the overlapping of this flap b provides a rounded edge for the lips of the user and prevents any tendency of the sharp .ed e of the cup from cutting the lips.

I! the form of cup shown in Figs. 8 and 9, the flap b is of curved form as illustrated in the blank shown in Fig. '2, it being like the-flap 6 shown in Figs. 5, 6 and 7 bent down along the line f. to lock the side edges. i

In Fig- 8 the side edges are folded, in the mannerlshown in Fi 5, while in Fig. 9. the side edges are folde in the manner shown in Fig. 6. In Figs. 10 and 11, in addition to the flap b, the slde edges are locked at the lowe'medges b turning the lower corners of 'the cup int e manner indicated at k. In'

Fig. 10 these corners are illustrated as turned in one direction, while in Fig. '11

they are illustrated as turned in the o positetional direction. The corners form an ad lockigg means, but not as eflicient as' the flap b of 7 1g Figs. 12, 13, 14 and ,15 illustrate c lindri cally formed cups formed from blan s, such as that illustrated in Fig. 4, in which each side a and d is provided with a pair of extensio s or separated flapsb and e, which when t e cu is'formed as shown in Fig.,12- with theirsl'de edges. folded, areturnedin- .Wardl as illustrated at b in 12 althoug they may be turned outwardly. In are s.:5, 6 and 7.

cup, while in Fig. 14 they are folded inwardlytoward each other at on along the bottom of the cup. In Fig. 15 the flaps may be folded in the manner shown at n, that is, inside instead of outside the cup. In Figs.-

. 13, 14 and 15 it will be understood that the upper flap 1) shown in Figs. 5, 6 and 7 may also be used in addition if desired to the lower flaps Z, m and n, or the style of flap 6 of Fig. 12 may be used in addition to the lower flaps Z, on and n. In all the forms of the cup shown, it will be ObSGI'VBdnthfit- I have provided an efficient locking means for locking the side edges against detachment, which locking means may be formed at either end of the cup orat both ends when preferred, but in practice I have found that the simplest and most easily folded form of locking means is that shown in Figs. 5, 6, 7, 8 and 9. In practice the lockingfiap .b may be in the form of a coupon if desired.

In practice, the cup may bemade liquidproof by the use of paraffin paper, or by coating paper with paraffin or other suitable substance, and this may be helpful in preserving the edges of the paper as Well as securing the locking flap in position, although the improvement is not confined thereto.

As shown in Figs. 5, 6, 7, 8 and 9 in the present improvement, When-the side edges.

' of the cup are infolded in the manner shown,

particularly in the preferred form of cup shown in Figs. 5, 6, 7, 8 and 9, these same folds extend across the flap b so thatwhen the flap is bent down the infolded portions are bent upon themselves at the crease formed by the bending of the flap 7) thereby refolded, and the flap with its folded side 1 edges folded down upon thecupthereby to lock the side folds thereof. 7

2. A sanitary drinking cup comprising a blank folded upon itself transversely thereby to "form a pair of flat sides, one of said sides having a flap extending beyond the other at the open end of thecup, said sides and flap having. their side edges folded and infolded, ,and the flap with its folded side edges folded down upon the cup thereby to lock the side folds thereof.-

3. A sanitary drinking cup comprising a blank folded upon itself transversely thereby to form a pair of flat sides, one of said sides having a flap extending beyond the other at the open end of the cup, said sides and flap having their side edges folded and refolded to lock the same without the use of paste, and the flap with its folded side edges folded down upon the cup thereby to'lock the side folds thereof, said eup also having folded bottom portions with both foldedside edges thereof folded therewith,
